Application filed April 13, 1885. Serial No. 162,089. (No model.) Patented in Germany March 22. 1885, No. 33,301; in France March .23, 1885, No. 167,825; in England March 24, 1885. No. 3,796, and in Austria-Hungary July 22, 1885, No. 11,501 and No. 37,927.

To all whom it may concern.-

Be it known that I, ANTON ZEMANN, a subj ect of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Rose-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of roseengines by means of which closed or jointed undulatory curves can be traced having a general circular or elliptic form.

The object of my invention is to improve this class of engines; and it consists in the construction, arrangement, operation, and combination of its several parts, substantially as hereinafter fully described.

In the drawings hereto annexed and forming a part of this specification, Figure l is a front elevation, partly in section, of my improved rose-engine. Fig. 2 is a sectional side elevation thereof; Fig. 3, a plan view, and Fig. 4 a detail view.

A indicates the bed or supporting-plate, upon which the operative devices are secured. It is provided with an opening, a, in this case of annular form, though it may be of other form, and a a are indices on opposite edges of the opening by means of which the apparatus is set in proper position upon the plate operated upon, and upon which plate the apparatus is set, the graver working in said opening a.

B B are curved arms, secured to the plate A by means of screws 1) b passing through feet I) b,formed on the lower end of said arms, and through plate A. At their upper ends the arms B have a horizontal portion, N, which terminates in a head, b in which is secured, by means of screws b, a guide-rail, O, the lateral faces of which are beveled in opposite directions, as shown in Fig. 2. Upon this rail is mounted a carriage, D, in which is secured the rosette or pattern carrier, consisting of a short cylinder or sleeve, E, that projects through a longitudinal slot. 0, Fig. 2, formed in the guide-rail C, said cylinder or sleeve E forming a bearing for the operating shaft F, which extends above and below said sleeve. Immediately below the vguide-rail the carrier E carries a worm-wheel, G, loosely mounted thereon, and below the worm-wheel are arranged the pattern disks or rosettes, also loosely fitted on sleeve E, but rigidly connected therewith and the worm-wheel G by means of a feather or spline, h, (shown in dotted lines in Fig. 1,) so that said plates may be removed and others fitted in their places. The worm-wheel G gears with an endless screw, G, that has its hearings in the carriage D,by means of which screw the patterns are adjusted around the sleeve E, as may be desired. It will be seen that by connecting the rosette or pattern carrier rigidly with the carriage D through the adjusting-screw said carrier remains stationary when the shaft F is rotated.

As more clearly shown in Figs. 1 and 2, the sleeve E has an annular flange, e, that serves to secure the same, by means of screws 6, to the upper face of the carriage D, and an extension, e projecting above the flange e, that serves as a seat for a disk, I, in which is formed a slot, i, Fig. 3, through which the shaft F passes.

Upon the heads 12 of the arms B are secured stop-plates B, Figs. 1 and 3, that hold the disk or chuck I against movement with the carriage D, and upon' said disk I are secured bearings z" for a screw, J, that operates in a block or nut, f, secured to shaft F, which latter carries at its upper end the operatingcrank F, by means of which it is rotated. It is obvious-that if the screw J is rotated the shaft F will be moved laterally in the slot 2' of 0 eccentric to the center of disk I and rotated the latter will be caused to oscillate between the stop-plates B; but when said shaft is concentric with the center of the disk the shaft will carry the disk along with it, and a reciprocating movement will be imparted thereto on the guiderail C.

To the lower end of shaft F is secured an arm, K, from which is supported the style or graver, and the intermediate mechanism that imparts the oscillatory or undulatory movement to the said graver or style, which move ment is controlled by one of the patterns or rosettes H on the carrier E. This mechanism is constructed and arranged as follows: L is the style or graver, supported from a carrier-arm, M, pivoted to the lower end of a frame, N. The forward end of the arm has a slot, m, along which the style may be adjusted by means of a thumb-screw, that passes through the styleholder L, through suitable clamping-plates, and the slot m. The graver or style is adj ustable in a slot of the holder L by means of a set screw, 1. It will be seen that the graver bears upon the plate under operation with a force corresponding to its own weight. This may, however, be increased by securing to the car.- rier a suitable weight, m, Fig. 1, to cause the graver to bear upon the plate to be engraved with greater or less force, according to the weight applied.

The frame N, that supports the carrienarm M, is pivoted to a carriage, O, on vertical pivotal screws n n, that pass through bracketarms a n, and have their hearings in suitable blocks secured to the upper and lower faces of the carriage 0, so that said frame N can oscillate on its verti'pivotal screws. The carriage O is arranged to slide on a V-shaped guide-rail (shown in dotted lines in Fig. 1) in a direction at right angles to that of carriage D, said guide-rail being secured to the arm K, on the lower end of the operatingshaft F, by means of a screw or screws k or otherwise. From the inner face of the car riage 0 projects a lug, 0, in the threaded perforation of which operates an endless screw, Q, that has its bearings in the ends of the guide-rail P, by means of which screw the carriage O can be adjusted along said rail.

R is a plate arranged to oscillate on horizontal pivotal screws 0' r, Fig. 2, that have their hearings in the ends of the carriage O. The plate It bears against a pin, S, that passes loosely through a sleeve or bearing, 8, and the opposite end ofthe pin bears upon' the periphery of one of the patterns or rosettes H. The bearing 8 of the pin S is adj ustable vertically in a slotted or forked standard, In, secured to the arm K, at the lower end'of shaft F, as more plainly shown in Fig. 1, so that said pin may be brought in contact with any one of the patterns or rosettes on carrier E. On the frame N is arranged a pin, T, that is adjustable vertically and horizontally, as shown in Fig. 4-. A plate-spring, U, is secured to the carriage O, which spring tends to constantly force the frame N inwardly or toward the plate R, the pin T impinging upon said plate. When the shaft F is rotated, the irregularities in the peripheral configuration of the pattern or rosette H, with which the pin S contacts, and the power exerted upon frame N by the plate-spring U, cause the pin S to reciprocate in its bearings, and as this pin, as well as the pin T, bears upon opposite sides of plate R, an oscillating movement is imparted to the latter on its pivots, as well as to the frame N, that carries the style or graver. The latter consequently follows the movements of the frame N, and said style will therefore trace an undulatory curve, the form of which will depend upon the peripheral configuration of the pattern-disk H that actuates the pin S and on the position to which the pin T'is adjusted,that is to say, on the distance of the latter from pin S, which distance determines the amplitude of the vibrations or oscillations of plate R, and consequently those of the frame N, and through them, the amplitude of the undulatory curves traced by the graver.

From the foregoing description it will be seen that, irrespective of the undulatory movement imparted to the graver L by the pattern or rosette, the said graver will not change its position when its point lies in the plane of the axis of the shaft and when the latters axis lies in the plane of the axis of the disk Ithat is to say, if the pattern were a perfect disk, and the parts were in the described position, the point of the graver when the shaft E is rotated will rotate upon itself as a fulcrum. When, however, the position of the point of the graver L is changed relatively to the vertical axis of shaft F, by means of the adjustingscrew Q, so that said point will be in a plane eccentric to the plane of the axis of the shaft, always supposing the" pattern or rosette to be a perfect disk, the graver will rotate around the axis of the shaft F when the latter is rotated and traces perfect circles. On the other hand, when the axis of the shaft F is displaced relatively to the axis of the disk I, and the point of the graver brought into the plane of said shaft, it will trace straight lines; and, finally, when the shaft is in the last-described position, and the point of the graver placed in a plane eccentric to that of the shaft, ellipses will be produced.

It will beseen from the foregoing that straight as well as curved lines are produced by the engine, and that by means of the pattern or rosette-of which one form is shown in plan view in Fig. 4tand by means of the adj usting devices described any desired undulations may be given to these lines. V V V are pointers for the screws J, G, and Q, the heads of which are or may be provided with suitable indices to indicate the extent of the adjustment of the parts displaced thereby.
